tachment to their shaft of. the cylindrical brushes which scavenge the combing icy-lin ders of Heilmann type combers. In such mach nes the combing cylinders are mounted on the common combshaft, journaled in a series ofintermediate frame uprights, one

between each pair of cylinders, and thero-v tary brushes for such cylinders are similarly mounted on a common brush shaft, also journaled in the same uprights between each pair of adjacent brushes. As the brushes become worn out, new ones have to be secured to the shaft, and it is desirable that the brushes be removable without requiring 1 the shaft to be withdrawn from its set of journal boxes in the uprights. The .present invention provides a brush mounting whereby the brush stock, divided into two parts or halves, can be clamped around the shaft, between bearings, and fixedly secured thereto, and whereby it can be easily removed and replaced when necessary. The invention also concerns the structure of the brush itself, whereby its useful life is prolonged and replacements rendered necessary only at infrequent intervals, all as will be hereinafter fully set forth and claimed.

In the drawings forming part hereof,

Figure 1 is an elevation of a comber brush and part of the next adjacent brush, showingthe bearing for the brush shaft and also a portion of a comb cylinder in section;

Fig. 2 is an end elevation of the brush, partly in section; and

Fig. 3 is a side elevation ofthe end of a brush, partly in section.

In Fig. 1 the combing cylinder is marked 1, its shaft 2, the brush shaft 3, and the intermediate frame upright 4. The shafts 2.

and 3 are both journaled in the upright 4, and it will be understood, as above stated,

that there is a similar upright at each endof each brush and cylinder in the comber.

The scavenger brush is formed of two semicylindrical brush stocks 5, each equipped withradial bristles, which forthe present may be assumed-to be of ordinary vegetable fiber such common to use for this purpose.

The stocks are each provided with sem1- cylindrical grooves on their proximate faces, adapted to fit upon and around the brush shaft 3. Each brush stock is Ordin'ari'lyand conveniently made of wood and iscircumferentially'rabbeted at each end and 'shod with a semi-circular metal end or shoe '6, which fits and fills the wooden rabbet, projecting' beyond the wood as a virtual e'xtensionof the stock itself. 'Theshoes Gare fastened to the stock in anysecure manner, as by means of one or more wood'screws, indicated at 7. Each shoe is also circumferentially rabbeted so that when the two brush stocks are placed around the shaft 3, asub- V stantially continuous circular rabbet-groove will be thereby formed to receive and serve as a seat for the locking-ring 8. The'se rings 8 encircle the brush shaft and are placed thereon when the said shaft is first installed in the comber, two being left'between each pair of uprighs The width of the rings is such that when one is placed adjacent to each brush shaft journal (9 in Fig. 1) there will yet be space enough between them-in which .to place the two brush stocks uponthe shaft,

the metal shoes, the three radial screws 10 in the latter are set up to force the halves of the brush together and clamp them fast upon the shaft. Sufficient clearance is allowed between the wooden faces of the stocks to allow them to be so tightened, and also to be further tightened if after a period of use they become loose. When the brush is worn out, it is removed by unscrewing the ends of the rabbeted shoes, as will be evident, and it will be noted that there are no parts to hamper the free use of the screw-driver or wrench used in the operations of assembling same: screws and slipping the rings off the r are accessible on the outer or peripheral or disassembling the brush, since the screws faces of the rings.

The bristles 11 are preferably made of vegetable fiber, as above stated, and wear thereof is retarded by incorporating in them a series or row of 'metallic bristles 12, one of such series or rows being desirably applied at about the middle of each half brush stock and extending the full length of the other rows of bristles. These metallic bristles are fine steel wires mounted in card clothing 12 tacked to the brush, and each wire is spaced from the others so that it possesses the full degree of resilience resulting from its fineness and length. The gentle rubbing of these hard, but yielding, steel wires upon the needles of the combing cylinders appears to keep them brightly polished Without any scoring or scratching, so that wear of the vegetable bristles takes place at a slower rate than would otherwise be the case, and the life of the brush as a whole is prolonged.

ilhe metallicbristles even when spaced from each other, however, are slightly stiffer than the vegetable bristles and can therefore remove bunches of cotton from the combing cylinder which the other bristles alone could not pick up, the result of which is to keep the cylinder and the sliver produced thereby in a cleaner condition than is otherwise possible. It will be understood'that the brush and cylinder are so rotated that the combing needles on the latter pass through the bristles of the brush in the direction to wipe the dirt ed the points of the needles, the latter being inclined as usual. This relationship of the parts avoids dulling the needle points by contact with the metal bristles,

notwithstanding the traverse motion usually imparted to the brush shaft. I

I am] aware that steel wire bristles have heretofore been used in brushes for textile and other uraoses but I believe in self to be the first to have utilized the combination 2. The combination in a comber, of a comb cylinder and rotary scavenger brush coacting therewith, comprising a relatively wide group of vegetable or organic bristles and a relatively narrow" row of slender metallic bristles.

3. A scavenger brush construction for combers comprising in combination with the comb cylinder, a rotary scavenger brush composed of assembled brush stocks, each stock carrying several rows of vegetable or organic brush bristles and a less number of rows of elastic, slender, wire bristles adapted for engagement with the comb cylinder.

In testimony whereof, I have signed this spec1ficat1on 1n the presence of two witnesses.
